__past__ continues "The new version of the Apache license will apply to all Apache projects, including the popular web server and many Java libraries like Xerces and Log4J, and making it easier to integrate Apache- and GNU-licensed code was one of the primary goals for its development. With the new license being GPL-incompatible (just like the older Apache licenses were), it is not possible to distribute programs that use libraries covered by under it and others covered by the GPL.
Apparently, the FSF does not actually consider the patent-related clauses a bad idea, let alone non-free - it is just that they impose a restriction that the GPL does not, and that makes the license automatically incompatible. It might even be that GPL Version 3 will include similar statements or at least allow them, as a message from FSF legal counsel Eben Moglen indicates. Additionally, prominent Apache hacker Roy Fielding claims that it doesn't really matter what the FSF thinks about the matter, because according to the Apache Software Foundation, derived works can just be distributed under the GPL."
